Abstract: An imaging system for a printer utilizing a friction belt drum drive is comprised of a drum position sensor, drum pulley, drive belt, motor pulley, drive motor, drive motor position sensor, and controller. The velocities of the drum and motor drive pulleys are measured using the controller and position sensors. These velocities along with the drive ratio are used to determine and monitor slip between the belt and pulleys. The magnitude of the slip measured can be used to trigger the controller to respond to the slip event. These responses may include, for example, disabling the motor or reducing motor current or providing a warning indicative of an excessive slip event. Slip measurement combined with other measurements such as motor current can be used to determine the torque capacity of the friction drive. Further, long-term changes in the ratio of pulley velocities can be used to determine drive belt wear.

Abstract: PROBLEM TO BE SOLVED: To perform more accurate adjustment of printing process parameter by measuring media in a printer by a transfer subsystem.
SOLUTION: The printer includes an intermediate imaging member 12, a transfer roller 94 located proximate to the intermediate imaging member 12, a displaceable linkage for moving the transfer roller 94 to the intermediate imaging member 12, and a controller coupled to the linkage. The controller is configured to compute a media thickness from a measured movement of the transfer roller 94 from the first position to the position where a transfer nip is formed to the intermediate imaging member 12 without an image substrate 404 being in the transfer nip, and a measured movement of the transfer roller 94 from the first position to the position where the transfer nip is formed with an image substrate 404 in the transfer nip between the transfer roller 94 and the intermediate imaging member 12.

Abstract: PROBLEM TO BE SOLVED: To maintain the state of aligning a print head with a transfer surface of a drum assembly, in a transfer inkjet printer. SOLUTION: The print head 18 faces the transfer surface 34 of the drum assembly 38. Contacts 74 and 76 are formed between the print head 18 and the drum assembly 38. The contacts include a contact member which is supported by the print head, and a receiving member which is supported by the drum assembly; and the contact member and the receiving member are brought into contact with each other. A driving member is moved along a print head transfer surface. In this case, the contact member and the receiving member, which constitute the contacts, are kept in the state of contact with each other while sliding, and the print head is kept in the state of being aligned with the drum transfer surface.

Abstract: PROBLEM TO BE SOLVED: To constantly maintain an alignment state in a positional relationship between a transfer drum and a printhead in an offset printing system.
SOLUTION: The printhead 18 is energized toward a transfer drum 26 through a head tilt spring 70 to make contact and is determined for position relative to the transfer drum by contact points 74 and 76 in between. Stub shafts 60 and 62 pivotally support the printhead and are slightly permitted for movement against the chassis. The force for driving the printhead in the direction of connecting the two stub shafts (X-axis) acts on the X-axis and contributes to the maintenance of the alignment state.

Abstract: PROBLEM TO BE SOLVED: To provide an improved method for processing a signal of an encoder home position. SOLUTION: This method is configured in such a manner that: an absolute home magnitude signal is created by adjusting widths of a plurality of bars of an encoder disk related with a code wheel having a code wheel surface rotating vertically with respect to the rotation shaft; a variation rate signal is created by sampling the absolute home magnitude signal; the signal to a noise ratio is enhanced by filtering the variation rate signal; and the home position of the variation rate signal is determined by applying home positional algorism. A characteristic configuration of the variation rate signal enhances the robustness of the home position related with the variation rate signal, and the effectiveness of the rendering device is enhanced by effectively processing the signal of the encoder home position.
